The TELESYNC TSI-2069 E1 ISDN Termination Unit can be used in three different modes.

Test Mode: The TSI-2069 provides a dial-up means of automatically looping back or generating BERT patterns on any or all of the 30 DS-0 B channels in an E1 ISDN data stream. The ISDN Termination Unit can be used to test Nx56/64 kb/s, H0, H11, and H12. The TSI-2069 uses the ISDN D-channel to accept or originate calls using Q.931 protocol. In addition to call termination, call origination and BERTS measurements, the TSI-2069 captures up to 1000 D-channel messages and saves them in a log file.

Thru Mode: The TSI-2069 can be installed in the customer E1 ISDN line (either central office or customer location) to monitor the bidirectional D-channel protocol. Access and control is through the RS-232C interface, Ethernet interfaces or dialed up through a B-channel using a TSI-2069 or equivalent.

Cross Connect Mode: The TSI-2069 functions as a network element to terminate the Switch (Network) D-channel and cross connect the Network calls to the DXC (Terminal) E1 based on called phone numbers. The TSI-2069 can also perform Mode 1 bonding of the incoming calls before cross connecting. The Cross Connect capability is used to interface ISDN dial-up services to packet or fractional E1 networks.

Monitor Mode: The TSI-2069 functions as a two channel Protocol Analyzer connected to the Digital Cross Connect (DCS) in the C.O. The PRI from the ISDN switch and the CPE are bridged into the TSI-2069. The Monitor Mode is used to capture, log and analyze the D-Channel protocol transactions from the Switch and the Customer directions. This is a useful mode when the customer is having problems originating and/or receiving calls.
